Bats
Learn about the bats of the San Diego River
There are 23 bat species in San Diego County, and 5 of these species are at-risk. The San Diego River Watershed is home to at least 16 different bat species.
The San Diego River Park Foundation is raising awareness about these amazing critters which are so important to the river's ecosystem, and sharing what we've learned from documenting bats at many places along the San Diego River and its tributaries.

What's so cool about bats?
- Bats are vital to our ecosystem
- Bats help by distributing seeds
- Bats are great pollinators
- Bats eat mosquitos and other pests
- Bats use echolocation to navigate and can determine size, shape, speed, and direction as they detect different features
- Bats are the only flying mammal
Join a Bat Walk
We host monthly educational bat walks from May through October. If you would like to learn more about bats and observe them in their natural habitat, join us for a walk!
Contact Natalie or call us at 619-297-7380 to learn about our next event. Please note that since we see less bat activity in the cooler months, we may not hold an event until the spring when it gets warmer.
